A systematic review of the epidemiology and clinical characteristics of artificial stone-related silicosis and dust protection / 中华劳动卫生职业病杂志

Objective: To investigate the epidemiology, clinical characteristics, on-site dust monitoring and individual protection of the patients with artificial stone-related silicosis. Methods: In March 2022, the literature on artificial stone-related silicosis published from January 1965 to February 2022 was searched in China Journal Full-text Database, Wanfang Database, VIP Database, EMbase and PubMed. Chinese and English search terms include "silica dust""silica dust""silicosis""artificial stone""pneumoconiosis", etc. References were included according to inclusion and exclusion criteria, and data were extracted. The epidemiological characteristics, natural course of disease, workplace dust concentration and individual protection level of patients with artificial stone-related silicosis were analyzed by systematic review. Results: A total of 30 literatures were included, including 7 cohort studies, 14 cross-sectional studies, 3 case-control studies and 6 case reports. A total of 1358 patients with artificial stone-related silicosis were diagnosed from 1997 to 2020, with an average age of 41.5 years old and an average dust exposure time of 11.3 years. Among them, 36.2% (282/778) had progressive mass fibrosis or accelerated progressive silicosis at first diagnosis. Chest imaging showed diffuse small nodule shadow, pulmonary fibrosis, and silico-alveolar proteinosis. Pulmonary function showed restricted or mixed ventilation disorder with or without decreased diffusion volume. The disease progressed rapidly, with progressive mass fibrosis, respiratory failure, and even death. Patients engaged in artificial quartz stone processing, with high concentration of silica including ultra-fine particles, most of which were dry operation, lack of on-site ventilation measures and no effective personal protection. Conclusion: The artificial stone processing workers suffer from artificial stone-related silicosis due to dry cutting, lack of on-site dust removal facilities and personal protective measures, and the disease progresses rapidly, leading to poor prognosis.

Clinical features and prognosis of core binding factor acute myeloid leukemia children in South China: a multicenter study / 中华儿科杂志

Objective: To analyze the clinical features, efficacy and prognosis factors of core binding factor (CBF) acute myeloid leukemia (AML) children in South China. Methods: This was a retrospective cohort study. Clinical data of 584 AML patients from 9 hospitals between January 2015 to December 2020 was collected. According to fusion gene results, all patients were divided into two groups: CBF-AML group (189 cases) and non-CBF-AML group (395 cases). CBF-AML group were divided into AML1-ETO subgroup (154 cases) and CBFβ-MYH11 subgroup (35 cases). Patients in CBF-AML group chosen different induction scheme were divided into group A (fludarabine, cytarabine, granulocyte colony stimulating factor and idarubicin (FLAG-IDA) scheme, 134 cases) and group B (daunorubicin, cytarabine and etoposide (DAE) scheme, 55 cases). Age, gender, response rate, recurrence rate, mortality, molecular genetic characteristics and other clinical data were compared between groups. Kaplan-Meier method was used for survival analysis and survival curve was drawn. Cox regression model was used to analyze prognostic factors. Results: A total of 584 AML children were diagnosed, including 346 males and 238 females. And a total of 189 children with CBF-AML were included, including 117 males and 72 females. The age of diagnosis was 7.3 (4.5,10.0)years, and the white blood cell count at initial diagnosis was 21.4 (9.7, 47.7)×109/L.The complete remission rate of the first course (CR1) of induction therapy, relapse rate, and mortality of children with CBF-AML were significantly different from those in the non-CBF-AML group (91.0% (172/189) vs. 78.0% (308/395); 10.1% (19/189) vs. 18.7% (74/395); 13.2% (25/189) vs. 25.6% (101/395), all P<0.05). In children with CBF-AML, the CBFβ-MYH11 subgroup had higher initial white blood cells and lower proportion of extramedullary invasion than the AML1-ETO subgroup, with statistical significance (65.7% (23/35) vs. 14.9% (23/154), 2.9% (1/35) vs. 16.9% (26/154), both P<0.05). AML1-ETO subgroup had more additional chromosome abnormalities (75/154), especially sex chromosome loss (53/154). Compared with group B, group A had more additional chromosome abnormalities and a higher proportion of tumor reduction regimen, with statistical significance (50.0% (67/134) vs. 29.1% (16/55), 34.3% (46/134) vs. 18.2% (10/55), both P<0.05). Significant differences were found in 5-years event free survival (EFS) rate and 5-year overall survival (OS) rate between CBF-AML group and non-CBF-AML group ((77.0±6.4)%vs. (61.9±6.7)%,(83.7±9.0)%vs. (67.3±7.2)%, both P<0.05).EFS and OS rates of AML1-ETO subgroup and CBFβ-MYH11 subgroup in children with CBF-AML were not significantly different (both P>0.05). Multivariate analysis showed in the AML1-ETO subgroup, CR1 rate and high white blood cell count (≥50×109/L) were independent risk factors for EFS (HR=0.24, 95%CI 0.07-0.85,HR=1.01, 95%CI 1.00-1.02, both P<0.05) and OS (HR=0.24, 95%CI 0.06-0.87; HR=1.01, 95%CI 1.00-1.02; both P<0.05). Conclusions: In CBF-AML, AML1-ETO is more common which has a higher extramedullary involvement and additional chromosome abnormalities, especially sex chromosome loss. The prognosis of AML1-ETO was similar to that of CBFβ-MYH11. The selection of induction regimen group FLAG-IDA for high white blood cell count and additional chromosome abnormality can improve the prognosis.

Emerging pathogenic role of group 3 innate lymphoid cells in inflammatory diseases / 生理学报

Group 3 innate lymphoid cells (ILC3) as a family member of innate lymphoid cells (ILCs), have been defined as novel innate immune cells in the past decade. ILC3 include a variety of heterogenous subsets with different phenotypes and functions, which are mainly distributed in barrier organs such as the intestine, lung and skin. They play an important role in immune regulation, tissue repair and lymphoid tissue formation. However, in various inflammatory diseases, ILC3 become dysregulated and participate in the pathogenesis through secreting a series of cytokines such as interleukin (IL)-17, IL-22, interferon-γ (IFN-γ) and granulocyte-macrophage colony-stimulating factor (GM-CSF) to modulate other immune cells and induce the formation of ectopic lymphoid structures. Therefore, it is of great significance to explore the phenotype and function of ILC3 in order to advance the understanding of inflammatory diseases and find new therapeutic targets. In this article, the phenotypic characteristics, biological functions and research progress of ILC3 in inflammatory diseases were reviewed.

A method for measuring the ADCP potency of anti-CD38 monoclonal antibody / 药学学报

A method to measure the antibody-dependent cell-mediated phagocytosis (ADCP) potency of anti-CD38 mAb was developed based on design of experiment (DoE) with a Jurkat/NFAT/CD32a-FcεRIγ transgenic cell line as the effector cell, the Daudi cell line as the target cells, and luciferase as the detection system. The DoE method was used for optimization of experimental parameters and methodological validation. The results show that anti-CD38 mAb exhibits a dose-response relationship with the following four-parameter equation: y = (A - D) / [1 + (x / C)B] + D. Several experimental parameters were optimized by statistical experimental design and determined as follows: the working concentration of anti-CD38 mAb was 800-20.81 ng·mL-1, the density of the target cells was 7.5×104 per well, and the density of effector cells was 2.5×104 per well, with an induction time of 6 h. The method showed good specificity. The recovery rate for samples from 5 different groups showed that the relative potencies of anti-CD38 mAb were (59.97 ± 4.74) %, (82.44 ± 5.15) %, (110.69 ± 11.71) %, (129.23 ± 5.22)% and (162.15 ± 3.66) %. The recoveries ranged from 103% to 120% and the RSDs of the above results were all less than 11%. The linear detection range was 50%-150%. Based on DoE design, this method for measuring ADCP potency of anti-CD38 mAb was optimized and validated with good specificity, repeatability and accuracy. This method can be used for evaluation of ADCP biological activity of anti-CD38 mAbs.

Molecular biological characteristics of the 2019 novel Coronavirus in Shijiazhuang / 中华检验医学杂志

Objective:To analyze the molecular epidemiological characteristics of the Corona virus disease 2019 (COVID-19) cases in Shijiazhuang, which can reveal the origin of the outbreak and provide a scientific basis for COVID-19 prevention and control.Methods:From January 2 to January 8, 2021, a total of 404 samples from 170 COVID-19 cases were collected from the Shijiazhuang Fifth Hospital. The consensus sequence of 2019 novel Coronavirus(2019-nCoV) was obtained through multiplex polymerase chain reaction-based sequencing. The sequences of 170 COVID-19 cases were analyzed by the PANGOLIN, and the data were statistically analyzed by T-test.Results:Among the 404 COVID-19 samples, a total of 356 samples obtained high quality genome sequences (>95%,100×sequencing depth). The whole genome sequences of 170 COVID-19 cases were obtained by eliminating repeated samples. All 170 sequences were recognized as lineage B1.1 using PANGOLIN. The number of single nucleotide polymorphism arrange from 18-22 and most of the single nucleotide polymorphism were synonymous variants. All of 170 genomes could be classified into 48 sub-groups and most of the genomes were classified into 2 sub-groups (66 and 31, respectively).Conclusions:All cases in this study are likely originated from one imported case. The viruses have spread in the community for a long time and have mutated during the community transmission.

A Resting-state Functional Magnetic Resonance Imaging Study of Whole-brain Functional Connectivity of Voxel Levels in Patients With Irritable Bowel Syndrome With Depressive Symptoms

Background/Aims@#Depressive symptom is one of the most common symptoms in patients with irritable bowel syndrome (IBS), but its pathogenetic mechanisms remain unclear. As a voxel-level graph theory analysis method, degree centrality (DC) can provide a new perspective for exploring the abnormalities of whole-brain functional network of IBS with depressive symptoms (DEP-IBS). @*Methods@#DC, voxel-wise image and clinical symptoms correlation and seed-based functional connectivity (FC) analyses were performed in 28 DEP-IBS patients, 21 IBS without depressive symptoms (nDEP-IBS) patients and 36 matched healthy controls (HC) to reveal the abnormalities of whole brain FC in DEP-IBS. @*Results@#Compared to nDEP-IBS patients and HC, DEP-IBS patients showed significant decrease of DC in the left insula and increase of DC in the left precentral gyrus. The DC’s z-scores of the left insula negatively correlated with depression severity in DEP-IBS patients.Compared to nDEP-IBS patients, DEP-IBS patients showed increased left insula-related FC in the left inferior parietal lobule and right inferior occipital gyrus, and decreased left insula-related FC in the left precentral gyrus, right supplementary motor area (SMA), and postcentral gyrus. In DEP-IBS patients, abstracted clusters’ mean FC in the right SMA negatively correlated with depressive symptoms. @*Conclusions@#DEP-IBS patients have abnormal FC in brain regions associated with the fronto-limbic and sensorimotor networks, especially insula and SMA, which explains the vicious circle between negative emotion and gastrointestinal symptoms in IBS. Identification of such alterations may facilitate earlier and more accurate diagnosis of depression in IBS, and development of effective treatment strategies.

Interlaboratory method validation of HPLC-FMA for determination of polysorbate 80 in monoclonal antibodies / 药学学报

The high performance liquid chromatography-fluorescence micelle assay (HPLC-FMA) method for the content determination of polysorbate 80 in monoclonal antibody drugs was validated to study its applicability and transferability between various laboratories, and the feasibility to be included in the Chinese Pharmacopoeia. Both J.T. Baker and Nanjing Well-sourced polysorbate 80 was used in the collaborative validation of polysorbate 80 content analysis in seven different laboratories. The results show that when the protein concentration was no more than 20 mg·mL-1 and the concentration of polysorbate 80 ranged from 0.05 to 0.5 mg·mL-1, the method had good specificity. The recovery rates of the spiked samples ranged from 92.20% to 117.70% for J.T.Baker and from 93.90% to 117.20% for Nanjing Well. The intra-laboratory precision (%RSD) was less than 4.30% for J.T. Baker, and less than 2.60% for Nanjing Well, while the overall precision was less than 5.45% for J.T. Baker, and less than 6.70% for Nanjing Well. The linear correlation coefficient was more than 0.98 for J.T. Baker and more than 0.99 for Nanjing Well. The results of the collaborative validation prove that the HPLC-FMA method has good accuracy, precision, linearity, and specificity, and could be used for release control analysis of polysorbate 80 content in monoclonal antibodies across different laboratories.

Children were most prone to suffer from asthma attacks at the turn of seasons (87/259 cases, 33.59%). The frequency of asthma was the lowest from June to August (9/259 cases, 3.47%). Among 244 cases attacked by acute asthma, the prevailing time period of acute attacks was irregular in 88 patients (36.07%), bedtime in 64 cases (26.23%). In different regions of the city, the lowest prevalence rate of asthma was found in Binhu District (50/1 830 cases, 2.73%), the highest prevalence rate of asthma was found in Xinwu District (71/1 502 cases, 4.72%), the difference between the highest and lowest prevalence rates of asthma was significant ( χ2=13.19, P<0.05). In terms of the air quality in different admi-nistrative regions of Wuxi, the nitrogen dioxide (NO 2) concentration, the carbon monoxide (CO) concentration, PM 10 and PM 2.5 in Binhu District were lower than other 4 regions.In different seasons in Wuxi city, the sulfur dioxide(SO 2) concentration, the NO 2 concentration, the CO concentration, PM 10 and PM 2.5 from June to August were significantly lower than those in other months.The prevalence of asthma in children in different administrative districts of Wuxi was weakly positively correlated with the SO 2 concentration, the NO 2 concentration and PM 10 ( r=0.10, P<0.01; r=0.22, P<0.01; r=0.06, P<0.01, respectively). The prevalence of asthma was weakly negatively associated with the ozone(O 3) concentration ( r=-0.06, P<0.01). Acute asthma attacks were weakly positively correlated with the SO 2 concentration ( r=0.22, P<0.01), the NO 2 concentration ( r=0.28, P<0.01), the CO concentration ( r=0.23, P<0.01), PM 10 ( r=0.18, P<0.01) and PM 2.5 ( r=0.18, P<0.01), and weakly negatively correlated with the O 3 concentration ( r=-0.40, P<0.01). Conclusions:The prevalence of asthma in Wuxi is higher in boys than in girls, and the frequency of asthma attacks is related to the season.The SO 2, NO 2, CO, PM 10, PM 2.5 and O 3 concentration affect the prevalence and acute attacks of asthma.

A qualitative study on the driving forces of postpartum health promotion in gestational diabetes / 中国实用护理杂志

OBJECTIVE@#To investigate the therapeutic effects of puerarin on rats with type 2 diabetes mellitus (T2DM).@*METHODS@#T2DM models were established by high fat and high glucose feeding combined with a one-time intraperitoneal injection of streptozotocin (STZ, 60 mg/kg). Then the rats were randomly divided into normal group, model group, metformin group (MET, 40 mg/kg), puerarin low-dose group, medium-dose group and high-dose group (40, 80, 160 mg/kg), n=10. After the model was successfully established, rats were treated with corresponding drug intervention by intragastrical administration for 4 weeks. The body weight and fasting blood glucose (FBG) were measured per week, and blood samples were collected 24 h after the last administration, and serum levels of blood glucose, serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholestrol (HDL-C), serum enzyme activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), serum creatinine (SCr), and blood uric acid (UA) were measured.@*RESULTS@#As compared with normal group, the body weight was decreased after 4 weeks-intervention in the model group, and the levels of FBG, TC, TG, LDL-C, ALT, AST, BUN, SCr and UA were all increased,while HDL-C level was decreased (P＜0.05). As compared with model group,the body weight was increased after 4 weeks-intervention in metformin group and puerarin groups, and the levels of FBG, TC, TG, LDL-C, ALT, AST, BUN, SCr and UA were decreased (P＜0.01); meanwhile, HDL-C level was increased significantly (P＜0.05).@*CONCLUSION@#Puerarin can reduce the weight loss of T2DM rats, decrease the blood lipid and blood glucose levels of T2DM rats, which can be used to control T2DM.

Colon participates in activation of oxidative stress in rats with chronic renal failure / 第二军医大学学报

Objective To explore the mechanism of gastrointestinal dysfunction caused by chronic renal failure (CRF), and to determine whether colon is involved in the activation of oxidative stress (OS) in CRF. Methods Thirty male SD rats were randomly divided into control group (n＝10) and CRF group (n＝20). The rats in the CRF group were treated with 5/6 nephrectomy to establish CRF model, and the rats in the control group were only sutured after opening renal capsule. The rats were sacrificed at 10 weeks after model administration, and the serums and colon tissues near ileocecal valve were collected. Blood urea nitrogen (BUN) and serum creatinine (SCr) were measured to evaluate the success of the model. Malonodialdehyde (MDA), superoxide dismutase (SOD), total antioxidant capacity (TAC) and 8-hydroxy deoxyguanosine (8-OHdG) in the serum and colon tissues were detected to evaluate the level of OS. The ubiquinol cytochrome C reductase core protein(UQCRC1) was tested for the evaluation of mitochondrial function. Results Compared with the control group, the levels of BUN and SCr in serum of the rats in the CRF group were increased, suggesting that the model was successfully established. Compared with the control group, serum and colonic MDA levels were significantly increased in the CRF group (P0.05); however, there were no significant differences in 8-OHdG or anti-oxidative markers (SOD, TAC) in serum or colon tissues between the two groups (P0.05). The protein level of UQCRC1 in colon tissues was significantly reduced in the CRF group compared with the control group (P0.05). However, there was no significant difference in the mRNA level of UQCRC1 in colon tissues between the control and CRF groups (P0.05). Conclusion There is an imbalance between oxidation and antioxidation in the colonic tissues of CRF rats, which may be related to mitochondrial dysfunction.

Transcatheter arterial chemoembolization for hepatocellular carcinoma complicated by portal vein tumor thrombosis: prognostic analysis / 介入放射学杂志

Objective To investigate the potential prognostic factors in patients with hepatocellular carcinoma (HCC) complicate by portal vein tumor thrombosis (PVTT) who are treated with transcatheter arterial chemoembolization (TACE). Methods The complete clinical data of a total of 46 patients with HCC complicate by PVTT, who were treated with TACE during the period from January 2010 to March 2016, were retrospectively analyzed. Clinical material database was established. Kaplan-Meier test was adopted to analyze the survival rate and the COX risk ratio model was used to screen out the independent prognostic factors. Life table method was employed to calculate the survival time. Results The 6-, 12-, 18- and 24-month survival rates were 51. 2％, 28. 9％, 23. 4％ and 10. 2％, respectively. The median survival time was 6. 7 months. According to mRECIST standard, complete remission (CR) was obtained in one patient (2. 1％), partial remission (PR) in 11 patients (23. 9％), stable disease (SD) in 16 patients (34. 8％) and progress disease (PD) in 18 patients (39. 2％). Multivariate analysis indicated that local tumor response, ascites, cholinesterase, and arteriovenous fistula were the independent factors affecting the prognosis. Conclusion The independent prognostic factors that affect the survival time of HCC patient include local tumor response, ascites, cholinesterase and arteriovenous fistula.

Establishment of a mouse model of chronic renal insufficiency induced by repeated administration of cisplatin / 中国实验动物学报

Objective To observe the changes of renal tubular injury and the extent of interstitial fibrosis in the C57BL/6 mouse models of chronic kidney disease(CKD),and provide experimental animal evidence for study of the pro-gression of acute kidney injury(AKI)to chronic kidney disease as well as its mechanisms. Methods Twenty-four 8-week-old male C57BL/6 mice were randomly and equally divided into control group, low-dose, medium-dose, and high-dose cisplatin groups,6 mice in each group. Mice in the cisplatin groups were administrated with 5,7 or 10 mg/kg cispla-tin by intraperitoneal injection once a week for 4 weeks. Plasma creatinine and 24-hour urinary protein were detected to as-sess the renal function. The mice were sacrificed, and plasma and kidney samples were collected for subsequent tests. Pathological changes were observed using periodic acid-Schiff(PAS)staining. To evaluate renal tubules injury, the ex-pression of kidney injury molecule 1(KIM-1)was examined by immunohistochemistry and the level of urinary N-Acetyl-β-D-glucosaminidase was detected with a commercial kit. The infiltration of CD3-positive T cells and F4/80-positive macro-phages was observed by immunohistochemistry(IHC)and immunofluorescence. The expression of collagen I and α-smooth muscle actin(α-SMA)were tested by immunohistochemistry to assess the renal fibrosis, while total kidney collagen was detected by Picrosirius red staining. Results In contrast to the normal control group,the kidney injury became more seri-ous in the cisplatin-treated mice as cisplatin concentration increased. Particularly,significant kidney damage was observed in the high-dose cisplatin group. Compared with the control group,the plasma creatinine and 24-hour urinary protein were significantly increased in the high-dose cisplatin group(P<0.05 and P<0.001)indicating impaired renal function. Mor-phologically,numerous clear vacuoles and necrosis were present in renal tubule epithelial cells in the high-dose cisplatin group. The expression of KIM-1 was markedly up-regulated and the level of urinary NAG was elevated. Infiltration of CD3-positive T cells and F4/80-positive macrophages was enhanced in the mice of high-dose cisplatin group. Data from immuno-histochemistry and picrosirius red staining showed that mice of the high-dose cisplatin group developed renal fibrosis evi-denced by markedly up-regulated expression of collagen I and α-SMA. Conclusions Repeated administration of 10 mg /kg cisplatin for 4 weeks can induce chronic renal insufficiency in mice,which may serve as a novel model for the research on underlying mechanisms of progression from acute kidney injury to chronic kidney disease.
